Title: Gear knob
Inventor: SENNETT MICHAEL T
IPC: G05G1/10
Filed: 1988-03-02
Granted: 1992-02-04
Abstract: Abstract of the Disclosure A knob for a gear lever comprises a cap, a gripping section having an axial bore through it and gear teeth about one end of the bore, and an annular anti-rotation member having an axial bore through it and gear teeth about each end of the bore.  When assembled, a stem of the cap passes through the axial bores of the gripping section and of the anti-rotation member.  The gear teeth of the gripping section mesh with the gear teeth of the anti-rotation member and prevent the member from rotating with respect to the gripping section.  A base has an axial bore through it and gear teeth about one end of the bore.           The bore has inwardly projecting ribs between which, when the knob is assembled, a spline of the stem of the cap fits at substantially all rotational positions of the spline relative to the base.  The gear teeth of the anti-rotation member mesh with the gear teeth of the base and prevent the anti-rotation member from rotating with respect to the base.

Title: Character recognition algorithm
Inventor: TAKAHASHI HIROYASU
IPC: G06K9/68
Filed: 1988-08-25
Granted: 1992-04-21
Abstract: CHARACTER RECOGNITION APPARATUS                       Abstract A recognition dictionary of a tree structure is created by using multi-value feature with maximum and minimum values such as a white run length, rather than a binary feature value such as black or white pels, so that the dictionary can be created through very simple operations with fewer samples.  In addition, recognition error due to erroneous branching can be detected at the time of searching of the dictionary tree by using a ternary tree instead of a binary tree, to improve the efficiency in the recognition.  Combination of the recognition technique with the tree structure dictionary and the pattern matching technique also provides a feature where the former can efficiently narrow down the candidate character categories, and then the latter can order the candidates.  Thus, because high speed and high recognition ratio can be realized, and the processing is simple, a practical system can be implemented on a general purpose personal computer in software only, without using special hardware.  Additionally, it is easy to improve the recognition ratio through adaption because addition or modification of the recognition dictionary can be very easily performed.

Title: Stereolithographic beam profiling
Inventor: SPENCE STUART T
IPC: B29C67/00
Filed: 1989-04-17
Granted: 1995-01-24
Abstract: An apparatus and a method for profiling the intensity of a beam and thus measuring the overall intensity and power of a beam are disclosed that have particular use in stereolithography.  A beam sensor comprising a pinhole in a plate and a photodetector behind the pinhole measures the intensity of portions of a beam as the beam is moved over the beam sensor.   Software  associated with the sensors in a computer controls the scanning mechanism for the beam so that the beam is shifted to find the pinhole and move across it in order to develop the intensity profile.  The invention can be used to detect drift in the scanning mechanism, determine the focus of the beam, and predict the depth and width of photopolymer cured by the beam.  A related apparatus and method for calibrating and normalizing a stereolithographic apparatus is described, and a related apparatus and method for correcting for drift in production of objects by stereolithography, is also described.

Title: High efficiency disk format and synchronization system
Inventor: LEIS MICHAEL D
IPC: G11B20/14
Filed: 1989-05-11
Granted: 1992-11-10
Abstract: ABSTRACT       A disk drive system provides all required synchronization, positioning, validation, and data functions within each disk sector.  All of these functions are provided within two zones, a header section and a data section.  The header section includes a preamble, a synchronization character and an address field, as well as servo information for track following.  The data section of each sector includes a data preamble, a data synchronization character, a bad sector bit map, the data and data redundancy information. The header section of at least one sector in a track includes a short DC-erase field, a transitionless segment which is used in synchronization.  To synchronize a read/write head to the disk, the system first detects the DC-erase field. The system next searches for the header preamble and synchronization character.  If it finds them within predetermined times, it then looks for a valid sector address to complete the synchronization.  If the system does not detect the preamble and synchronization character within the predetermined times, it looks for another DC-erase field and continues the synchronization process.  After the preamble and synchronization character are found, the desired sector is located by reading the addresses of the succeeding sectors.

Filed: 1989-06-01
Granted: 1996-06-11
Abstract: A receiver for a digital data transmission system comprises a sampling device for sampling digital data signals received from a subscriber loop.  A precursor equalizer connected to the output of the sampling device equalizes, in effect filters, the sampled digital data signal.  A timing recovery circuit connected to the output of the precursor equalizer controls the sampling device in dependence upon the filtered digital data signal.   The precursor equalizer has a difference equation such that the equalized digital data signal has at least one zero-crossing occurring substantially one baud before the main cursor of each pulse.   For twisted wire pair subscriber loops, the precursor equalizer may have a difference equation:   w(n)=      which   produces   a   single   precursor   zero-crossing.            Alternatively, the precursor equalizer may have a difference equation: w(n)=               which produces two precursor zero crossings, y(n) being the input to the filter, w(n) its output, ho the main cursor height before equalization and h-1 the precursor height before equalization.          The latter precursor equalizer may be modified by multiplying each of the coefficients (h-1/h0)2 and h-1/h0 by a factor .delta. =      to define the zero crossing more precisely.            A (1-Z-1) filter may be provided ahead of the precursor equalizer.
